Abstract

Magnetisable core-shell microspheres consisting of a core of magnetisable fillers and a shell of crosslinked organopolysiloxane. <??>They are obtained by dispersion in an organic solvent of an aqueous suspension of magnetisable fillers not coated with dispersing agent, dissolving an organopolysiloxane SiVi and an organohydropolysiloxane SiH in the organic phase, crosslinking, removal of water, separation and optionally redispersion of the magnetisable microspheres in water.
